The actual issue with the update
The actual issue with the update is that everything that has been built and added to the game since it's release was based on the old gameplay. Troop cost, upgrade costs, and mine and pump creation rates were all based on the amount of resources players were getting under the old way of playing the game and what it took for them to upgrade at a reasonable rate. This new way may have been the way the game was intended, but it's not they way it was built. You changed the core of the game but left all the pieces the same, they just don't fit together anymore.
Resource rates need to increase and the amount of loot you can take from lower THs needs to decrease. The reward for being in higher leagues needs to increase, as it is now there is ZERO incentive to collect trophies.
If this is truly how gameplay was intended you need to adapt all facets of the game, don't just change the core and stop there.
